Two details in Robert Wayne Arnao's disappearance pull in different directions. He was 41 when he left his home in Key West on December 17, 1991, and he didn't take his medication or any extra clothes. That usually points away from a planned departure. But he also drove off in his own car, a blue 1988 Oldsmobile Cutlass Ciera with dark tinted windows, Florida plate FZY76X, and neither he nor the car has ever been found.

Key West only has one road out. A car leaving the island in 1991 had to go up U.S. 1 through the Keys, and a car going into the water somewhere along that route is a real possibility that would explain both details.

He's 6'1", about 160 pounds, with brown hair and eyes and a gunshot scar on the center of his abdomen. The Monroe County Sheriff's Office lists him as endangered missing. Has anyone heard whether the canals or waterways along U.S. 1 were ever searched for that car?
